Ezra 6
19And the sons of the exile performed the Passover on the fourteenth day of the first month,

20for the priests and the Lĕwites had cleansed themselves – all of them were clean. And they slaughtered the Passover for all the sons of the exile, and for their brothers the priests, and for themselves.

21And the children of Yisra’ĕl who had returned from the exile ate together with all who had separated themselves from the uncleanness of the gentiles of the land in order to seek יהוה Elohim of Yisra’ĕl.

22And they performed the Festival of Unleavened Bread seven days with joy, for יהוה caused them to rejoice, and turned the heart of the sovereign of Ashshur toward them, to strengthen their hands in the work of the House of Elohim, the Elohim of Yisra’ĕl.
